摘要

用60Co标准源和HPGe探测器对狭缝式裂变中子探测系统（电流型）的γ灵敏度进行了实验探索研究

并计算了同样的235U-HPGe系统结构的理论能谱

实验能谱与理论能谱一致

进而得出235U-PIN系统的γ辐射灵敏度。

Abstract

The sensitivity of slot-collimated PIN fission neutron detecting system(electrical current type) to γ-rays was studied by using an HPGe detector(counter type) and a 60Co source.Gamma-ray energy spectrum from a 235U-HPGe system of the same structure was simulated.The measured energy spectrum agreed well with the simulated spectrum.By replacing the HPGe with PIN

we obtained the γ sensitivity.
